First claim
Opening claim text (preview).
The invention claimed is: 1. A fluororesin material comprising a melt-fabricable fluororesin and having a dielectric constant of 2.1 or less and a dielectric loss tangent of 0.00020 or less at 12 GHz, wherein the total number of functional groups consisting of —CF=CF 2 , —CF 2 H, —COF, —COOH, —COOCH 3 , —CONH 2 , and CH 2 OH per 10 6 main-chain carbon atoms of the fluororesin is 6 or less, and wherein the fluororesin is at least one copolymer selected from the group consisting of a tetrafluoroethylene/(per)fluoro(alkyl vinyl ether) copolymer and a tetrafluoroethylene/hexafluoropropylene copolymer. 2. A fluororesin material for high-frequency transmission comprising the fluororesin material according to claim 1 . 3. A coated electric wire for high-frequency transmission comprising the fluororesin material according to claim 1 as an insulating coating layer, wherein the insulating coating layer is a solid insulating coating layer.
